Claims. (Cl. 30-34) This invention relates to dry shavers of the typewherein there are cutter heads including cutter elements at least one ofwhich is moved at high speed relative to the other. One form of shaverto which the invention is applicable is shown in US. Patent No.2,561,241 issued July 17, 1951 to Jan Streng.

A main object of the invention is to provide a shaver the head of whichcan be passed over the face with much greater ease and smoothness andwith substantially no irritation to the skin.

A further object is to achieve the above object while at the same timenot reducing shaving efficiency by hampering the reception of hair intothe usual shearing slots in the head.

Yet'another object is to provide a shaver structure wherein the amountof hair reception areas exposed may be varied by variations of thepressure with which the shaver is applied to the face thus enablingheavy or light beards to be removed with equal facility.

In brief and general terms, the invention includes the feature ofrelating rolling comb elements with respect to the cutter elements,whether the cutter elements are elongate or curvilinear, in such mannerthat the comb elements, or some of them, are always moved in advance ofthe cutter elements to contact the skin first and permit the shaver tobe moved smoothly and easily over the face of the user.

A further feature relates to the provision of rolling comb elements oneach side of elongate cutter elements and so mounting them that they canbe readily removed for adjustment and repair.

A further feature relates to the provision of means whereby the rollingcomb elements may be mounted for relative movement to said elements orto yield to varying pressure of the shaver against the face of the userso that the action is efiicient for either light or heavy beards. Tothis latter end the rolling comb elements are mounted at their ends byresilient means to permit this yielding, in a detailed manner to besubsequently described.

Still a further feature relates to the provision of structure wherebythe rolling comb elements may be mounted directly on the shaver headitself or may be mounted on the hair pocket casing.

A further feature relates to the provision of rolling comb elementswhich may be smooth elongate rollers, corrugated rollers, balls or disksand the like.

Further features of construction will be understood from the followingdetailed description especially when taken in connection with theaccompanying drawings which form part of the specification hereinafterset forth.

Present preferred forms which the invention may assume are illustratedin the drawings, of which,

Fig. 8 is a detailed vertical section taken on the line 88 of Fig. 7.

Fig. 9 is an exploded isometric view of the manner of supporting theends of certain comb elements;

Referring now to the specific forms which the invention may assume,attention is first directed to Figs. 1 to 4 inclusive in which it willbe seen that there is provided a shaver having a head portion 20, a hairpocket casing 21,

and cutter elements 22 which, in this form of shaver are pairs ofelongate cutter blades between which there is the usual relativereciprocal motion. The casing or cover 21 is constructed to be snappedinto the position shown by reason of grooves 23 in the head 20 and lugs24 on the casing 21. The casing 21 is provided with headed rivets 25 topermit a cover (not shown) to be snapped over the top of the casing 21.

In order'to reduce the friction occurring as the shaver head is movedacross the skin of the user whereby to make the shaving operation smoothand easy, it is contemplated to provide a series of rolling combelements or combing rollers associated with the cutting elements 22. Inthe form of cutting elements 22 shown which are elongate elements, thecomb elements assume the form of elon gate rollers. In the forms ofshaver shown in Fig. 1 there are two cutter elements and there are threeroller combs. One of these comb elements or rollers 26 is disposedbetween the cutter elements 22 and is in the form of a smooth surfacedcomb element. As shown in Fig. 3 this roller is mounted for axialrotation but is also supported so that it can be moved along its axis topermit its removal from the casing 21 when desired, for adjustment,replacement, and repair. As shown in Fig. 3, the comb element has anelongate bore 27 at one end in which is disposed a coiled spring 28backing the rear end of a slidable plug 29 the outer end of which isreduced in diameter to form a bearing pin 30. The end of the combelement at this end is crimped in slightly as at 31 to limit themovement of the plug outwardly of the bore. The other end of the combelement 26 is reduced in diameter to form rigid bearing pin 32. Thesetwo pins rotatably rest in recesses 33 in the casing 21 as shown.Recesses 33, see Figs. 3 and 4, have side walls providing bearingsurfaces for the cylindrical end surface portions of bearing pins 30 and32. Recesses 33 also have end walls 33' forming the inner end of therecesses providing bearing surfaces for the end surfaces of bearing pins30 and 32. By having these recesses 33 opening inwardly toward eachother, ready manual insertion and removal of combing elements or rollers26 and into the space between the wall portions of casing 21 adia-.

cent recesses 33 until it is aligned with the opposite re 3, cess133.combing roller. .26 or, 34 may then be manually moved with the action ofspring 28 so rigid bearing pin 32 will engage in the adjacent recess 33until the extremity engages the end wall in the recess.

clear that this comb element is free to easily rotate on its axis whileit also may be moved along its axis to permit its removal when desired.

Inthis construction, the two outer comb elements 34 have a corrugated orwavy outer surface as shown and are mounted for free rotation and axialmovement for the above purposes. However in this latter form the spring28 is housed in a bore 27 as before and the plug 29 rides partly thereinbut the outer portion of the plug 29 is enlarged in the form of a disk35 ridingin an enlarged bore 36. This form appears to give greaterstability to the parts.

In the modified form of the shaver shown in Figs.

structed for axial movement for removal as-above described with respectto the form shown in Figs. 3 and 4, although for convenience and toavoid repetition this specific construction is not shown'in Figs. 5-to 9inelusive.

In Fig. 5 it is seen that the hair pocket casing 21 in this form issnapped on to the head 20 in a slightly different manner than abovedescribed. In this form, the

head on opposed sides is recessed to receive tight-fitting thimbles 37in which are disposed balls 38 backed by springs 39. The outwardmovement of the balls 38 are limited by crimping in the outer edges ofthe thimbles as at 40. The adjacent faces of the casing 21 are providedwith recesses 41 into which the balls snap when the casing is moved intoposition as shown.

In Fig. 6 is shown in detail the manner of mounting the outer combelements 34. The end pins 30 and 32 thereof now project into elongateslots 42 which permit the pins. to move up and down therein. Theconstruction which permits this form of comb element to move up or downas a whole transversely of its axis is afforded by the provision of aleaf spring member 43 the middle portion of which is fastened, such asby rivets 44, to inwardly turned flanges 45 near the top of the casing21. The opposite ends of the leaf spring are turned up as at 46 and areapertured at 47 to receive the pins 30 and 32. Thus it will be seen thatas more or less pressure is applied by the user the comb elements 34will yield to allow for .more efficient operation on heavy and lightbeards, for heavy beards the pressure will be greater and for lightbeards the pressure may be less.

With regard to the resilient support of the inner comb element 26 shownin these figures reference may be had especially to Figs. 7, 8, and 9,in which it is seen that the ends of the pins 30 and 32 are tapered asat 48 and project into similar elongate slots 42. Referring to Fig. 8 itwill be seen that there is provided an upwardly extending bore 43 whichhas a shoulder 50 at its upper end: The width of the bore is slightlylarger than the width of the elongate slot 42 and the upper end of the"slot 42Textends slightly above the shoulder 50; A spring This opera tionis reversed in removing rollers 26 and 34 from en-- 51 in the bore 49 atits upper end bears against the shoulder 50 and at its lower end bearsagainst a tight fitting plug 52 which keeps the spring undercompression. As seen in Fig. 8 it is seen that the top of the spring 51bearing against the shoulder 50 is slightly below the level of the topof the slot 42 so that the tapered end 45 of the comb element end pinswill enter this space and,

due to the taper thereof will force the spring down slightly. Thiscompression of the spring by the pin willbeen shown as mounted indifferent manners itis cleai i that they all may be smooth-surfaced orcorrugated if desired and they may all be mounted in the same man-' Inany case all the'comb elements thus far described; are preferably,although not necessarily, mounted to be moved axially for removal asdescribed. While the comb elements have been shown in the specific formsas mounted on the hair-pocket casing, it is quite obviousthatthey' maybe mounted on the head of the shaver if no-hair f pocket casing isempoyed.
